JAMES NUTTALL, OF HEAP BRIDGE, NEAR BURY, COUNTY OF LANCASTER,

' ENGLAND.

SPECIFICATION forming part of Letters Patent No. 245,859, dated August16, 1881,

A Application filed March 19, 1881. (No model.) Patented in England May4, 1880.

To all whom it may concern Be it known that 1, JAMEs NUTTALL, of HeapBridge, near Bury, in the county of Lancaster, England, have inventedcertain new and useful Improvementsin the Methodof and Machinery forCutting Cards, (for which I have obtained a patent in Great Britain, No.1,882, bearing date May 4,1880;) and [hereby declare the following to bea description thereof, referonce being had to the annexed two sheets ofdrawings, forming part of this specification.

My improvements relate to the cutting of patterircards for looms, andthe invention consists in the machine for effecting the same asdescribed and claimed hereinafter with reference to the accompanyingdrawings.

In the drawings, Figure 1 is a side elevation of the improvedcard-cutting machine. Fig. 2 is a front elevation of the same. Fig. 3 isa vertical longitudinal section of the selectinghead. Fig. 4: is a sideview, and Fig. 5 a plan view, of the machine as fitted for operation bypower. Figs. 6 and 7 are detail views.

Similar letters of reference indicate corre- 2 sponding parts.

The portions marked 00 are the main frame of the machine, carrying theoperative mechanism. I

A is the selecting-head, sustained above the frame by slide-rods a, thatare fitted to move in suitable guides. The slide-rods aare fitted attheir lower ends with adjustable gibs, to which are connected the rods 9of eccentrics g, which are upon a cross-shaft, g, that carries acrank-handle for its operation, whereby the head A is reciprocated.

The parts of head A are as follows:

a is a cross bar connected to slide-rods a, formed with two rows ofhorizontal apertures,

that receive keys 0 (I, and two rows of vertical apertures, that receivepunches b.

a a are end plates, sustained on bar a and carrying cross-bars, on whichare l un g cranklevers e f, that connect respectively with the 5 upperand lower keys, 0 (I, there being a lever,

c or f, for each key.

0 f are selecting-needles, suspended from the levers e f and workingthrough suitable guides at the back of head A. These needles correspondin number with the levers cf, keys c d, and punches b.

y is a presser-plate carried by a rod, g, on which is a spiral springfor steadying the pattern-card when the selecting-head descends, whichplate is perforated for the needles 0 f to pass through.

There are spiral springs above collars on punches I), tending to pressthem downward, and the downward motion is limited by the collars bearingon a plate, a attached to the under side of bar a.

The chain of cards used as patterns in cutting fresh cards is carried bya four-sided head or block, j, which is hung on pivots in end plates ofsliding frame it, that is sustained on rods k fixed on the frame .70. Astrap, 1z ,connected to the frame It, sustains a weight, n, which tendsto draw the frame back from the head A.

p p for receiving the card to be out.

A shaft, Z, is sustained on the main frameot' the machine and carries apinion, m, that engages with arack attached to the under side of frameIt, and there is also fixed on shaft 1 a wheel or disk, l, and a pulley,from which a strap, q, passes to a treadle, q, so thatby pressure on thetreadle the shaft is turned. A lever, h, is hung at the side of wheel Z,and bears by one end on a cam, h, fixed on the operating-shaft, g, whileits other end is connected with a spring -arm or hand -lever, 2 placedabove frame or, and also at the side of wheel 1, which is provided witha series of pins projecting from one of its sides. The lever i isprovided with a lug, which engages with the pins on the disk l toprevent the shaft Z from turning, and thereby holding the frame In,carrying the pattern-head from being moved forward or drawn back by theweight 12, except when the lug on the lcveriis disengaged from the pinson the disk by being depressed by the operator or drawn down by the camit through the medium of the lever h.

On one pivot of the head j is fixed a plate, 0 from which four pins, 0,project, and on the main frame is hung a weighted arm or tumbler,projecting in the path of the lower pins,

To the front of frame k are attached nippers 7o 0, so that as the headymoves back it is given a quarter-revolution by the contact with thetumbler, while at the forward movement the tumbler is pressed downwithout effect.

At a is shown the chain of pattern-cards passing around head j.

On the front of frame are nippers p for receivin g the card to be out.

w is an adjustable steady-plate, over which the plate 0 passes at itsforward movement, so that the head j is prevented from turning duringthe cutting operation.

I) is a plate on which the cards rest while being cut, formed with holesfor the punches to enter, and b is a plate also perforated for thepunches and placed above the plate 12 so that the cards may passbeneath.

The operation is as follows: The operator presses down arm or lever 'iwith his hand, and depresses the treadle q, thus drawing forward theframe 70 with the pattern-cards; the nippers open,and a blank card isplaced between them. The treadle is then released, and the weight drawsthe frame It, with the patterncard, beneath the needlesc f, and blankcard beneath punches b,as required to cut the first two rows of holes;when the lever i is released, and the lug engaging with the pins on thediskl holds the said frame stationary. The main shaft is then operated,and the eccentrics bring down the selecting-head. In descending, eachneedle that strikes a blank space of the pattern-card raises the end ofits lever B or f, and the other end of the lever is moved to draw backthe key 0 or d, so that the corresponding punch bis pressed upward inthe aperture of bar a, instead of cutting the blank card, while eachselecting-needle that passes through a hole in the pattern-card does notmove the lever to which it is connected, and the key to which the leverconnects remains across the aperture in which the corresponding punch isfitted, so that the punch is forced through the card to be out. Thesepositions are shown in Fig. 3. The head A then rises, and the cam h,acting by lever h, draws down arm 6, which allows one peg of wheel 1 topass, and the weight n, acting through the rack and pinion, moves frame70 back a distance suflticient for the cutting of the second two rows ofholes at the next descent of the head. Two rows of holes are thus cut ateach revolution of the shaft.

The pattern-cards being in chain, the lacing and peg holes are filled,and consequently corresponding holes would not be cutin the blank cardsif provision were not made for that purpose. 1 form holes in the headj,near its ends, corresponding with the lacing and peg holes, for theselecting-needles to enter and bend or crank the corresponding levers eor f, so that their upper ends are above the ends of the head, insteadof the pattern-cards, and the levers that correspond with the middlelace-hole are connected by cross-wires with the levers that correspondwith the end holes, so that they will work together.

In the power-machine shown in Figs. 4 and 5 the peg-wheel Z has pegs innumber one for each two rows of holes in the card, and at intervals thepegs are placed at a greater distance apart to allow for the joining ofthe cards.

s is a ratchet-wheel fixed on shaft 1, and having the same number ofteeth as there are pegs.

s is a lever carrying a pawl that engages the ratchet-wheel.

t is a spur-wheel having studs 8 for moving lever s, and driven byapinion,-t, on shaft (1.

l is a spur-wheel on shaft 1.

p are chain-pulleys on the same shaft, carrying chains 19 which passalso over the chainpulleys p and carry the cards to be out, which willbe laced together.

jj are chain-pulleys keyed on a shaft, j driven by spur-wheels l and j*from shaft l. The chain-pulleys j drive chains j passing overchain-pulleys f, which chains carry the pattern-cards.

The lever t, actuated by cam 70, is fitted to stop the shaft l and thechains while the cards are being cut.

At the ends of the presser-plate 3 I make holes to fit pegs on thechainsj to secure the chains while the selecting-needles act on thepattern-cards. I use, also, a similar presserplate to hold the chains 19while the cards are being cut.

Having thus fully described my inveution,l claim as new and desire tosecure by Letters Patent 1. In machines for cutting cards,thecombination of a reciprocating head carrying the punches andselecting-needles, a traversing head carrying the pattern-cards andblanks, and mechanism,substantially as described,for giving anintermittent movement to the traversing head, substantially as shown anddescribed.

2. The sliding punches 1), keys 0 d, levers e f, and selecting-needles ef, in combination with the reciprocating head A and pattern block orcylinder j, substantially as shown and described, whereby the punchesand selectingneedles are operated by one motion of the head, asspecified.

3. The cam h, lever h, arm orlevcr 45, wheel I, provided with pegs,pinion m, frame 70, provided with a rack engaging the pinion,weight nand strap, and the pattern-head j, substantially as shown and described,combined for operation as specifiethwhereby the traversing frame ismoved back at every revolution of the operating-shaft, as specified.
